We report eight patients with metastatic malignancy who developed severe back and leg pain caused by ischiogluteal bursitis. Careful evaluation excluded the possibility of bony metastases. Ischiogluteal bursitis is an easily diagnosed condition that can be effectively treated with local injection of corticosteroids. Recognition of this disorder will allow prompt therapy and unnecessary evaluation expenses.

An unusual case of multiple brown tumors due to parathyroid carcinoma is reported. The patient presented with lower leg pain. Plain radiographs demonstrated multiple lytic lesions of the lower legs and a Tc-99m MDP bone scan depicted multiple areas of increased uptake suggesting skeletal metastases. Tc-99m sestamibi tumor scintigraphy showed multiple sites of tumor uptake in bones and a large area of increased uptake with a cystic component in the right lower pole of the thyroid gland. An open biopsy from the right tibial lesion revealed a brown tumor. A large parathyroid carcinoma with a necrotic cyst was removed. After parathyroidectomy and right thyroid lobectomy, the patient became free of bone pain and serum PTH levels normalized. A 9-month follow-up Tc-99m MDP bone scan demonstrated less intense uptake in the pelvis, tibia, and fibulae. Nine-month follow-up tumor imaging with Tc-99m MIBI revealed disappearance of the preoperative uptake of multiple brown tumor.

We describe a 60-year-old woman with leg pain. Although metastatic bone tumor and atypical cells mimicking signet-ring cells in the bone marrow picture were observed, systemic survey revealed no primary lesion. The patient died two months after admission from systemic progress of the disease. Autopsy revealed a small focus of adenocarcinoma within the right upper lobe of the lung and systemic metastases without any particular changes in the gastrointestinal tract. The tumor cells of the lung were diffusely positive for cytokeratin 7, whereas cytokeratin 20 immunoreactivity was weak and focal, and that supported the lung origin of the present tumor. Moreover, the tumor cells in the bone marrow showed a similar pattern in immunoreactivity. These findings suggest that cytokeratin 7 and cytokeratin 20 immunoreactivity is helpful for the premortem diagnosis of the metastatic tumor of unknown origin.

Prostate cancer most often metastases to regional lymph nodes and bones by hematogenous or lymphatic spread. Metastases to the supradiaphragmatic nodes are rare. A 56-yr-old male smoker with generalized lymphadenopathy was referred to our center with the complaints of weight loss of 15 kg and severe back and leg pain. On computed tomography of the thorax and abdomen, massive mediastinal, intra-abdominal, retroperitoneal, and inguinal lymphadenopathies with hydroureteronephrosis of the left kidney were noted. Excisional biopsy of left cervical lymph node revealed metastasis of prostatic adenocarcinoma and transrectal biopsy of the prostate disclosed poorly differentiated adenocarcinoma. Bone marrow aspiration biopsy, done for the differential diagnosis of anemia, also showed infiltration with prostate-specific antigen positive neoplastic cells. Supradiaphragmatic spread of prostate cancer has been postulated to be by a hematogenous route via the vertebral venous system, or Batson's plexus, accessible via direct extension from the primary cancer site.

The majority of spinal cord lesions observed in prostate cancer are related to extradural compression. Intradural (extramedullary or intramedullary) metastases are very rare. The authors report a case of probable carcinomatous myelitis secondary to prostate cancer in a 50-year-old man, 9 months after the initial diagnosis of advanced metastatic prostate cancer. Despite endocrine therapy initiated immediately after diagnosis, the patient rapidly developed leg pain due to vertebral osteolysis. He developed flaccid paraplegia despite radiotherapy of the lumbar spine combined with corticosteroid therapy and chemotherapy. Spinal cord magnetic resonance imaging (MRI) showed typical features of very probable carcinomatous myelitis in the cervicothoracic zone. The patient died shortly after without histological confirmation. Regardless of the primary cancer, intramedullary spinal cord metastases have a very poor prognosis. Based on a literature search, this case appears to be the first case related to prostatic cancer reported in the medical literature.

Metastasis to a lower-extremity bone is an extremely rare event in patients with endometrial carcinoma. A 64-year-old woman presented with progressive right leg pain but no gynecologic complaints. A diagnostic workup revealed primary endometrial carcinosarcoma with an isolated tibial metastasis. Though the patient received only local irradiation to the tibial lesion, complete resolution of symptoms resulted. Six months after the radiotherapy, the intraabdominal disease progressed and the patient died. We note that tibial metastasis is one of the possible presenting symptoms in patients with endometrial malignant tumors. Irradiation can improve their quality of life and so may be effective in the management of symptomatic tibial metastasis.

Metastases to the bones of the lower extremities from prostate carcinomas are rare and are usually associated with diffuse metastatic disease or primary tumors of the abdomen and lungs. I present the case of a patient who presented with lower leg pain and had undiagnosed prostate carcinoma. Unlike previous reports of prostate carcinoma, this rare case includes magnetic resonance imaging, histology, and medical management. This case is unique in its presentation and has not been described previously in the literature.

Cardiac metastatic squamous cell laryngeal carcinoma is rare. We report the case of a 49-year-old man with recurrent squamous laryngeal carcinoma presenting with right leg acute ischaemia and large mobile right and left cardiac masses. The patient has history of laryngeal squamous cell cancer surgically treated with total laryngectomy, thyroidectomy, and tracheostomy 2 years ago. He was admitted to our intensive care unit with acute right leg pain, left sided chest pain, hypotension 92/55, and tachycardia 112 bpm. On physical exam, he had a faint pulse of his right Posterior Tibial artery with a cold foot, but no discoloration. Heart sounds were normal with no murmur. Initial workup showed a Troponin of 0.27. An electrocardiogram showed sinus tachycardia, with inverted T waves in the Infero-lateral leads. Emergent surgical thrombectomy was done on his right leg with restoration of arterial blood flow to the affected limb. An echocardiogram showed a preserved left ventricular function with multiple areas of echogenic masses in all four cardiac chambers located at the annulus of the tricuspid valve, the right ventricular free wall and along the inter-ventricular septum. No intracardiac shunt was detected by contrast study. Computed tomography scan of the heart confirmed the presence of multiple exophytic intracardiac masses within the left atrium, the right ventricle, interventricular septum, and lateral free wall of the left ventricle. Immunohistochemical staining with cytokeratin of the emboli was consistent with malignant squamous cell carcinoma consistent with metastases of his known laryngeal squamous cell cancer.

Endometrial stromal sarcoma (ESS) is typically associated with metastasis to the abdomen, pelvis, and lung. We found three case reports of ESS metastasis to the bone (two to the thoracic spine, and one to the parietal bone). Our objective is to review the literature on ESS spinal and intracranial metastases and, report the first case of ESS metastatic to the lumbar paraspinal region and sphenoid bone. A 53-year-old female with ESS status-post radiation, chemotherapy, and pelvic exenteration surgery presented with right hip weakness, back pain, and radicular leg pain that were explained by chemotherapy-induced neuropathy, radiation-induced lumbosacral plexopathy, and femoral nerve and obturator nerve injury during pelvic exenteration surgery. During routine positron emission tomography, we found metastasis to the L3 lumbar spinal region. L3 laminectomy and subtotal resection of the mass was performed with tumor residual in the neuroforamina and pedicles. One month later, magnetic resonance imaging (MRI) performed for persistent headaches revealed a large lesion in the sphenoid bone that was biopsied transsphenoidally with the same diagnosis, but no further surgery was performed. She is intolerant of chemotherapy and currently undergoing whole brain radiation. Delay in the diagnosis and management of lumbar paraspinal and sphenoid bone metastasis of ESS likely occurred because of the uniqueness of the location and aggressiveness of ESS metastasis. Health care providers should be aware of potentially aggressive metastasis of ESS to bone, in particular the unusual locations of the lumbar paraspinal region and sphenoid bone.

Alveolar soft part sarcoma (ASPS) is a rare disease of the soft tissue. Although the disease is rare, it is refractory to chemotherapy and radiation. En bloc surgical resection offers the best chance of cure. In this article we report the case of a 28-year-old woman who presented with buttock and leg pain, bowel, bladder and gait impairment and a large mass in the sacrum. Following surgical excision, the lesion was proven to be ASPS. On pathology, the mass was TFE3 (transcription factor E3) positive, indicating the presence of the ASPL-TFE3 (novel gene-transcription factor) translocation. Following surgery, the patient had improvement in her pain and ambulation; however, she refused adjuvant therapy to pursue hospice care and succumbed to her disease 2 years after surgery. On a review of the literature, it was found that ASPS of the bone constitutes a rare and formidable subset of this disease. Further, metastases related to ASPS are common in the lungs, liver, brain, and lymph nodes. The degree of dissemination is a predictor of outcome, with 5-year survival of 81-88% in patients with local disease and only 20-46% in patients with metastatic disease at the time of presentation. Brain metastases at the time of presentation portend the worst prognosis.
